How to run this application

Running the project

Install dependencies

Make sure to install the dependencies with npm

npm install

Running a local Postgres instance

Make sure that you have a local Postgres instance running and that you execute the SQL statment in the migrations directory.

After you have created the tables, make sure that you update the config/index.js file with your Postgres configuration (hostname, port, password, etc)

Starting up the local server

You can then run the project by executing

npm run dev

API

POST /dev

Expected payload

{
    "email": "[email protected]",
    "firstName": "John",
    "middleNames": "Alexander Tom",
    "lastName": "Smith"
}

The server will return a 400 bad request error if the request body does not conform to the expected DTO (data transfer object).

This endpoint will normalize the firstName field by truncating the whitespace and by moving all names after the first space to the middle names field.

Please check out the ./dto directory to learn more about the expected request body.

GET /dev/:id

GET /dev/:id returns a developer associated with the specified id. Response format:

{
    "email": "[email protected]",
    "firstName": "John",
    "middleNames": "Alexander Tom",
    "lastName": "Smith"
}
